4 Claims.

This invention relates to a strip guiding at- V inafter fully described, illustrated in the accom panying drawing and specifically pointed out in the appended claims.

In describing the invention in detail, reference will be had to the accompanying drawing wherein like characters denote like or corresponding partsthroughout the several views, and in which:

Figure 1 is a fragmentary view ofa sewing machine showing the invention applied to the presser foot thereof and showing how the strip is guided upon the cloth so that the strip will be sewn to the cloth. I

Figure 2 is a section on the line 2-2 of Figure 1.

Figure 3 is a perspective view of one form of the invention.

Figure 4 is a view of the blank from which the device shown in Figure 3 is formed.

Figure 5 is a view of a blank from which the second form of the invention is composed.

Figure 6 is a perspective view of the second form of the device.

As is well known in making dresses and skirts a narrow strip is sewn at one edge to the edge of the dress or skirt, this strip being used to connect the edge of the hem of the skirt or dress to another portion of the skirt or dress and it is the object of my invention to provide means for guiding this strip to the needle of the sewing machine so that it can be sewn to an edge of the cloth of the skirt or dress.

The device shown in Figures 1, 2 and 3 is formed from a blank A, shown in Figure 4, and which is provided with the long fiat part a and the substantially L-shaped part a, which has one limb connected to a side edge of one end of the part a. The free end of the part a' slopes from one edge to the other as shown at a". A rounded tongue I extends from the outer edge of the part a a slight distance from the free end thereof. This blank is folded and bent to provide the upright 2 from the outer portion of the long part 'a and the rest of the said long part is bent to form the elongated flat loop 3 which has its ends slightly rounded, the bottom closed and the top is formed from a short portion which extends substantially at right angles outwardly from the upright 2 and a longer portion which extends inwardly from one end of the loop and the major portion of which is formed by the wide part of 5 the blank at the junction of parts a and a, so

, that the edge of part a of the blank is located adjacent the base of the upright 2 but spaced therefrom to form an entrance slot 4 for the strip. That limb of the part a which is connected with 10 the part (It extends rearwardly and the other limb is bent to the left over this first limb to form a flat small loop 5, from the top of which the tongue I extends rearwardly. The sloping edge a" of the part a is slightly spaced from the bottom part of the loop 5 asshown at 6 and by making this end a with a slope the loop 5 may be made larger at its rear end than at its front end. This is for the purpose of enabling the loop 5 to be placed over the prong of the presser foot X of the sewing machine as shown in Figures 1 and 2, though this formation of the loop 5 is not absolutely necessary, particularly in some sewing machines. The upper end of the member 2 is formed with a hole 1 which enables the device to be suspended on a projecting supporting member.

The modification shown in Figure 6 is formed from the blank B shown in Figure 5 and this blank is of substantially U-shape, to provide the long flat limb b and the short flat limb b. The free end of the long limb has the hole I therein and the free end of the limb b is also preferably made sloping as shown at b", and a tongue I extends from the upper side edge of the limb 17'. Of course, this form shown in Figure 6 is provided with the upright 2 having the hole I at its upper end and the large loop 3 is formed from the rest of the limb b and this loop is substantially of the same shape as the loop 3 in Figure 3 and has the slot 4' thereon. However, the loop 5', formed from bending the limb b" of Figure 5 to the right, is located to one side of the wide part formed at the junction. of the limbs b and b of the blank and in a plane above the same, with the tongue I projecting rearwardly from the upper edge of the loop 5'. A space 6 is left between the inner end of the loop 5 and the bottom thereof and this loop 5' also has its rear end larger than its front end, the same as the loop 5 in Figure 3.

As will be seen from Figures 1 and 2 the device shown in Figure 3 is used on the right hand prong of the presser foot while the device shown in Figure 6 is to be used on the left hand prong. The tongue I or I as well as the small loop has 5 sufficient resiliency to frictionally hold the device on the prong and the tongue also serves the purpose of preventing the device being pushed too far on the prong as it will engage a part of the presser foot and limit the distance the loop can be pushed onto the prong. The tongue curves upwardly, as shown. The strip S to be sewn to the cloth C is first passed through a guide G carried by an upper portion of the machine, shown in Figure 1, and then it is passed through the large loop 3 or 3 which guides the strip to the needle of the machine with one edge overlapping an edge part of the cloth so that the needle will sew said edge of the strip to said edge part of the cloth, as shown in Figure 2. The strip is guided into the large loop through the slot 4 or 4*. by the upright 2 or 2' so that the strip can be readily placed in the large loop and the following procedure may be used.

The bottom edge of a skirt or dress is placed under the presser foot and on top of this is placed the strip S. Then the needle of the machine is passed through the strip and cloth to hold the same together. The strip is then taken in the left hand and the'attachment in the right hand and then the attachment and the strip are moved together with the strip engaging the upright. Then while holding the strip the attachment is raised to cause the strip to enter the slot and then by sliding the attachment on the strip the strip will adjust itself in the large loop. Then the small loop is pressed over a prong of the presser foot so that the device will be supported irom the foot in a slightly tilted position, as shown in Figure 1. Then the machine can be started so as to feed the strip and cloth under the presser foot and the device will guide the strip with one edge overlapping an edge part of the cloth with the two edges under the needle so that they will be sewn together as Shown in Figure 2. If desired the device can be put in position first and then the strip can be pressed against'the upright which guides it through the slot into the large loop. n

It is thought from the foregoing description that the advantages and novel features of the invention will be readily apparent.

It is to be understood that changes may be made in the construction and in the combination and arrangement of the several parts provided that such changes fall within the scope of the appended claims.

Having described the invention, what is claimed as new is:

1. A strip guiding attachment for a sewing machine comprising a body part having a fiat loop forming portion through which the strip passes and said loop forming portion having a transverse slot therein for the entrance of the strip and a second loop forming portion for receiving a prong of the presser foot of the machine, said slot being in the top of the first loop forming portion and an upstanding part, the lower end of which forms a Wall of the slot.

2. A strip guiding attachment for a sewing machine comprising a body part having aflat elongated loop forming portion for the passage of the strip and a transverse slot therein for the entrance of the strip and a second loop forming part, slightly resilient for receiving a prong of the presser foot, the second-mentioned loop forming portion tapering forwardly and a rearwardly extending tongue connected with the rear edge of the upper part of the second lo'op forming portion for engaging part of the presser foot, said body part with its tongue being formed of a single piece of material.

3. A strip guiding attachment for a sewing machine comprising a body part formed of a single piece of material shaped to provide a loop forming portion for the passage of the strip, said portion having a transverse slot in its upper portion for the entrance of thestrip, an upstanding part on the loop forming portion at an edge of the slot, for guiding the strip through the slot, at second loop-forming portion for receiving a prong of the presser foot, the upper part of the loop of the first-mentioned loop forming part having a rear extension at that side of the slot oDDOsite the side from which the upstanding part extends and to which the second loopiorming portion is connected, and a rearwardly extending slightly resilient tongue connected with the rear edge of the top part of the second loopforming portion.

LA strip guiding attachment for a sewing machine comprising a body part having a fiat loop-like portion through which the strip passes, the top portion of which has a transverse slot therein for the entrance of the strip and a second loopforming portion for receiving a prong of the presser foot of the machine, said second loop forming portion being connected with the rear portion of the first loop forming portion and above the planeof the loop therein for causing the first loop to guide the strip under the presser foot when the second loop is engaging a prong of the presser foot.
